I am originating a new usage of the ✅. I hope it catches on, because in a sense it's mostly used this way now.

As portability is currently quite limited, the checkmark now indicates that I am actively using that instance, and that my other nonchecked instance identities are hibernating.

@five interesting, but why not put a ❌ on hibernating accounts instead ? Otherwise we would all put ✅, doesn't help readability.
@five @flogib I ended up going with the Mute sign, what do you think?
